Peregrine Drake + Venser, Shaper Savant + Mirror Room // Fractured Realm

Peregrine Drake

Venser, Shaper Savant

Mirror Room // Fractured Realm

How it works

1. Activate up to five lands by tapping them, adding at least 3.
2. Cast Peregrine Drake by paying 4.
3. When Peregrine Drake enters, it triggers twice. Resolve the first trigger, untapping five lands.
4. Holding priority, activate up to five lands by tapping them, adding at least 3.
5. Resolve the second Peregrine Drake trigger, untapping five lands.
6. Cast Venser either from your hand or from the command zone by paying 2 plus commander tax if applicable.
7. When Venser enters, it triggers twice, returning it and Peregrine Drake from the battlefield to your hand.
8. Repeat.

This wondrous loop relies on Mirror Room // Fractured Realm's static ability, which doubles every triggered ability generated by your permanents. When you cast Peregrine Drake, its land-untapping entry trigger goes off twice, completely refunding its casting cost with interest and generating a massive surplus of mana. From there, you deploy Venser, Shaper Savant, whose entry trigger also doubles to bounce both himself and the Drake right back to your hand. By repeating this cycle, you effortlessly manufacture infinite mana, endless enters-the-battlefield and leaves-the-battlefield triggers, and an unbounded storm count to overwhelm your opponents.
